Bug#221565: g++-3.3: bad code generation

["Bryce Wilcox-O'Hearn" <zooko@zooko.com>]

Package: g++-3.3
Version: 1:3.3.2-4
Severity: normal


Hi there!  Thank you so much for the Debian toolchain!

I use Crypto++ v5.0 [1], and I've noticed that the "generate a random
RSA key pair" function either seg faults or goes into an infinite loop.
I've learned that turning optimization off with -O0 or else downgrading
to g++ 3.2.3 solves this problem.

Talking to Graydon Hoare, he says that RedHat's version of g++ 3.3.2, 
"g++ (GCC) 3.3.2 20031022 (Red Hat Linux 3.3.2-1)", doesn't exhibit this bug.

I'd be happy to provide a test case if you want.  You just call the
following method from Crypto++ 5.0:

void Initialize(RandomNumberGenerator &rng, unsigned int modulusBits, const Integer &e = 17);

Regards,

Zooko
